How To Install kelbt on Fedora 34

kelbt is Backtracking LR Parsing

Introduction

In this tutorial we learn how to install kelbt on Fedora 34.

What is `kelbt`

Kelbt generates backtracking LALR(1) parsers. Where traditional LALR(1) parser generators require static resolution of shift/reduce conflicts, Kelbt generates parsers that handle conflicts by backtracking at runtime. Kelbt is able to generate a parser for any context-free grammar that is free of hidden left recursion.
